Benign overfitting in leaky ReLU networks with moderate input dimension

no code implementations11 Mar 2024 Kedar Karhadkar, Erin George, Michael Murray, Guido Montúfar, Deanna Needell

The problem of benign overfitting asks whether it is possible for a model to perfectly fit noisy training data and still generalize well.

Mildly Overparameterized ReLU Networks Have a Favorable Loss Landscape

no code implementations31 May 2023 Kedar Karhadkar, Michael Murray, Hanna Tseran, Guido Montúfar

We study the loss landscape of both shallow and deep, mildly overparameterized ReLU neural networks on a generic finite input dataset for the squared error loss.

FoSR: First-order spectral rewiring for addressing oversquashing in GNNs

1 code implementation21 Oct 2022 Kedar Karhadkar, Pradeep Kr. Banerjee, Guido Montúfar

On the other hand, adding edges to the message-passing graph can lead to increasingly similar node representations and a problem known as oversmoothing.

Oversquashing in GNNs through the lens of information contraction and graph expansion

1 code implementation6 Aug 2022 Pradeep Kr. Banerjee, Kedar Karhadkar, Yu Guang Wang, Uri Alon, Guido Montúfar

We compare the spectral expansion properties of our algorithm with that of an existing curvature-based non-local rewiring strategy.
